The following are the three types of responses: Open, Accepted: The computer responds and inquires if there is anything more it can assist you with. Closed, Not Listening: "This port is currently in use and unavailable at this moment," the computer says. Filtered, dropped, and blocked: The computer doesn't answer at all.
A port scan is a technique for identifying which ports are open on a network. Port scanning is similar to knocking on doors to determine whether somebody is home because ports on a computer are where information is transferred and received.
Security professionals use port scanning to identify any security vulnerabilities on a network since it identifies open ports and services available on that network.
Install a Firewall: A firewall can help protect your private network from unauthorised access. It is in charge of the exposed ports and their visibility. A port scan in process can potentially be detected and stopped down by firewalls.
